To all whom t may concern: c

Be it known thatzI, CLARENCE L. TAYLOR,

a citizen of the United States, and a resident` of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Apparatus for Finishing Car-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it apc pertains to make and use the same.'

My invention relates toan improvement in apparatus for` finishing car wheels, and it consists in a series of vrolls. adapted to engage the periphery or tread.` and sides of` a wheel blank and roll the latter into itsfinal 1 represents the base orwfraine of themachine, provided near its front end with brackets 2, separated sufficiently for the introduction of a wheelblank, 3 between them, the

adjacent faces of said bracketshaving horizontal slots inwhich `the mandrel 4, carrying the wheel blank 3 is supported, the horlzontal slots permitting the `mandrel tomove outwardly as the rolling ofthe wheel blank progresses. c y c The wheel blank 3` after having been formed, centered and punched, is placed on the centering mandrel 4, and the "latter mounted in the `slotted `brackets 2, after which the drivingrolls `5, which are shaped,

as more clearly shown inFig. 4, arelmoved intocontact with the wheel blank. 3 at the rear of the rim of the wheel blank ras shown n `in Fig. 1.

The driving rolls.` which `shape the rear of the rim of the blank,`or wheel 3,.'are fast on the shafts 6, which` are mounted inbearings 7 inA the `carriers.oiyhousings" 8..- TheseI c housings which are ,A constructed y as shown i in Figs. 1 and 4, are pivotallymounted at their rear ends onthe .posts 9, which are firmly secured in recessed seats 10 in the base or frame 1, and the saidfhousingsre'ston the `with the frame 1.` These brackets 15 `form `21. Shaft 21 `carries the larger pinion 22 ture shaft 24 of the `motor 25.

motors 25, the shafts A16 will be rotated slowly, and byreason of their screw threads housing outwardly so as ftodisengagethe rolls from the wheel blank, thuspermitting of the` removal of a finished wheel and the insertion of a blank. The screws `13 have a upper face of the base or frame 1 as shown in Fig. 4, and are held down ontosaid frame, c by the bent flanges 11 on the frame 1 engagingthe groove 12 in the front end of the housing. Each carrier or housing has a lim-` ited movement in the arc of a circle concentric with the posts 9, and each is moved by a screw 13, mounted in an internally threaded nut 14 carried by the brackets 15 integral bearings for the shafts 16 which are continnations` of the screws 133, and each shaft is provided with a pinion 17 which meshes with a smaller and wider pinion 18. Pinion 18 is madewider than pinion 17 so as t0 permit of the `necessary longitudinal movement of the shafts 16 and its pinion 17, and the shaft ofpinionllS, "carries pinion 19 which meshes with small pinion 20 on shaft which meshes withsmallpinion 23 on armac By `starting will also be moved longitudinally,.which lat-` ter movement in onedirection, forces and holds the rolls ,5c in contact `.with the wheel blank 3, while a reverse `movement.withdraws the screws and `ymoves the carriers `or z loose or swivel connection at their ends with the carriers, so tliatthereverse rotation of drive motors for the two screws are coupled,

or connected and actuated by a single switch A or controllerso that uniform movement of the-two screws will alwaysbe maintained.

Keyed to each shaft 6 is a bevel-gear 26 whichmeshes with a larger idle bevel gear 27 `loosely mounted on the `post 9. The two bevel gears 27 are driven by the bevel gears 100 28 fast `on the main drive shaft 29 which latter `is supported in bearings 30 on the frame 1.

Thebevel `gears 27 are arranged horizontally ion the base, that is with their axes 105 vertical, andserve as idler gears throiigh.

which the` power` istransmittedmfrom the y driving gears 28, to the gears `26""on`sliafts 6," and :they are separated-on a line parallel c with the position ofthe wheel blank 3,150 11W the screws will positively pull the carriers y outwardly away Vfrom the wheel 3,\and`the y that the normal position of the `main rolls 5 is at about an angle of sixty degrees to each other, and they operate as before explained to shape and compress the blank at the under or inner side of the rimior tread.

The face or tread of the wheel blank is shaped' by the roll 29a, best shown in F ig. 3. This roll 29a' is mounted in the carrier 30, which is journaled at the lower end on the bearing 31 soV as to permit the roll to be moved toward and away from the wheel blank 3, the construction being such that the carrier is securely guided laterally in the main frame 1. The housing 30a is connected by link' 32 With the front end of the screw shaft 33, the said shaft being supported and alsoA guided at itsfront end by the bearing 34. The threadedl end of the shaft 33 engages the internal threads of the nut 35, Which latter is journaled in thebearing 36 formed in the frame 1, and projects at the rear to' receive the. pinion 37 which is keyed,v to the end of the nut. This pinion 37 meshes with the small pinion 38 on shaft 39, Which latter carries the larger pinion 40 Which meshes with smaller pinion 41 on shaft 42. 'Pinion 43, keyed to shaft 42, meshes with the small pinion 44 on the armature sliaft 45 of the motor 46.

The tread roll 29a is constructed at its periphery, to form and impart final shape tothe tread and flange of the wheel, and it is forced and held in contact with the wheel blank 3, by the gearing described. The rolls 5'` act :as ank abutment or stop against the pressure exerted against the blank 3 by the roll 29?, and the latterpin turn acts as a stop` for the pressure" of the rolls 5 against the underside of the rim. The roll 29a is free to' revolve` in its housing, hence as the wheel`- blank 3 is rotated by the positive rotation ofthe rolls 5, the roll 29a will be revolved against' 'the treadof the wheelv by its frictiolnal contact Withv the latter.

4 7 are the guide rolls,. holdv the blank 3 in proper position with relation tothe rolls 5 and 29a, and also roll the two sides of the tread of the Wheel blank. They" are located as shown in Fig. 3, underneath the driving rolls 5 and close up to the latter and are journaled on the eccentric ends 48of spindles 49 Which are mounted to turn inthe obliquely arranged bearings 50, formed in the frame 1.

Shaft 53, passes from one end ofthe frame l over the two spindles 49, and is provided Withtwo Worms 52, which mesh respectively with the Worm wheels 51 on the spindles 49, so that by turning theV said shaft by means ofthe yhand wheel 54, the spindles will be rotated or. turned so as to' force the. guide rolls 47' against the opposite sides of the rimof the wheel, andl hold" them there by a pressure which maybe increased or dimin-A ished byturning the hand Wheel.

which operate to In the operation of the mill, a blank approximating the shape of a wheel is placed on the mandrel 4 and the latter with thel wheel therein is inserted in the mill. The drive rolls 5- are then moved inwardly until they are in contact with the inner side of the rim of the wheel; the tread roll moved into contact with the tread of the blank, and the guide rolls into contact with the opposite sides of the rim. If when the parts are thus assembled the drive shaft 29 be started, the gears 27 will be rotated, thus rotating the two shafts G and their main rolls 5. The rotation of these rolls, rotates the Wheel blank, and the contact of the latter with the tread roll 29 and guide rolls -117 causes them to turn. As the operation continues, the several rolls are gradually and slowly fed toward the blank thus compressn ing and rolling the rim into its final and finished shape. f

The large bevel gears 27 from which the rolls 5 areJ driven, are placed with their axes vertical and serve as idler gears through which the power is transmitted from the driving gears 28` on the main shaft 29, to the gears 26 attached to the rolls 5, thus dispensing entirely with universal joints.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departino' from the spirit and scope of my claims. LlIence I would have it understood v that Ido not wish to confine myself to the exact eonstruction and arrangement of parts shown and described, but

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. Ina mill for finishinv car wheels, the combination of a main rol to engage the inner face of the rim of the wheel, a shaft for said roll, a movable carrier for the shaft, an idler gea-r, the axis of the carrier being coincident With'the axis of the idler gear, a gear on the roll shaft meshing with the idler gear, gearing meshing with the idler wheel for rotating same, and means engaging the roll shaft carrier intermediate its axis and the roll for forcing the roll against its work.

2. In a mill for finishing car wheels, the combination of air idler' gear, means for rotating the same, a rotating shaft having a limited lateral movement in the are of a circle concentric with the axis of the idler gear, a roll onsaid shaft,-a gear on the shaft and meshing with the idler gear, and means having connection with the said shaft intermedi ate the axis of the idler gear and the roll for forcing the latterinto contact With and foi` moving it away from the wheel, a roll to engagethe tread of the wheel `and means for moving the said latter roll toward the wheel.

3. The combination with two idler gears, a driving shaft located above the latter, gear wheels on said shaft and meshing with the two idler gears for rotating same, two housings mounted to be moved laterally toward and away from the work, the laxes of the housings being coincident with the aXesof the idler gears, a shaft in each housing, a roll on each shaft, independent means engaging each housing intermediate its aXis and W the roll for forcing the latter toward the work and a gear on each shaft also meshing with the said idler gears.

4:. In a mill for finishing oar wheels, the combination of the two housings each jour naled at one end, a shaft mounted in each housing, a roll and a gear wheel on each shaft, idler gears meshing with the gear wheels on the shafts for rotating them, the axes of said idler gears being coincident with the journals of the housings, a screw engaging each housing intermediate its journal and its roll and nearer the latter, and gearing for actuating the screws whereby the housing may be moved laterally toward and away from the work.

In testimony whereof, I have signed this specification in the Ipresence ofI two subscribing witnesses.
